[0006]

SUMMARY OF THE INVENTION According to the present invention, a fluid supplied from a fluid inlet through a body case to a fluid tank such as a water tank or a bath tub or the like is supplied to a set fluid amount. When this happens, the on-off valve, such as a ball valve, is moved by the operating valve that moves due to the rise of the float, and the on-off valve seat is closed to automatically stop the flow of fluid from the fluid inlet. This is achieved by providing an automatic water supply valve.

[0007]

As described above, according to the present invention, the opening / closing valve (ball valve, etc.) of the automatic water supply valve moves when the fluid supplied to a fluid tank such as a water tank or bath tub reaches the set fluid amount. The inflow of the fluid from the fluid inflow port is automatically stopped by closing the on-off valve seat by closely mounting the on-off valve seat and the like.

According to this automatic water supply valve, the space can be reduced as much as possible, and the automatic water supply and automatic stop can be performed easily and reliably without requiring any manpower, and the cost can be reduced.
